Jarrod Dyson and Billy Hamilton, two guys possessed of the kind of speed that can change a game, have been on the same big-league field this week. So far, only Dyson – a.k.a. Zoombiya — has had a major impact. The McComb native and ex-Southwest Mississippi Community College star went 1-for-3 with a walk and scored twice as Arizona beat Cincinnati 5-2 on Tuesday night at Chase Field in Phoenix. Taylorsville’s Hamilton, nicknamed Bone, had a couple of hits but didn’t score or drive in a run. Dyson, hitting leadoff for the Diamondbacks, ran through a stop sign at third base to score his first run in the third inning; he beat the relay throw without a slide. “I was already at full throttle and it’s hard to stop me like that,” he told mlb.com. In the fifth, he singled, went to second on a wild pitch and scored the D’backs’ final run on an infield throwing error. Dyson went 0-for-3 with two walks and a steal in Arizona’s 12-5 win in Monday’s series opener. Hamilton was a quiet 1-for-4 in that game. Dyson is batting .185 with two homers, eight RBIs, 16 runs and nine steals in 42 games for an Arizona team that is contending in the National League West. Hamilton, typically the Reds’ 9-hole hitter, is at .213 with two homers, 14 RBIs, 24 runs and nine steals in 54 games for club that is scuffling at 19-37. Their teams meet again today in the series finale. Don’t blink – you could miss something.
